CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 14/077,580, filed on Nov. 12, 2013, and entitled “CONSTRUCTING VIRTUAL MOTHERBOARDS AND VIRTUAL STORAGE DEVICES”, the entirety of which is incorporated herein by reference.

BACKGROUND

Cloud operators lease computational resources to clients of the cloud operators, and the clients execute applications using the leased computational resources. This arrangement tends to be mutually beneficial for the cloud operators and the clients. For example, a client has access to relatively high-end computing equipment, which may be prohibitively expensive for the client to purchase and may further be cumbersome for the client to maintain. The cloud operator, due to economies of scale, may be able to purchase a server computing device at a lower price compared to a price the client would have to pay for the server computing device. Furthermore, the cloud operator can employ professionals to maintain the servers and other hardware.

Typically, a client of a cloud operator will set forth a request indicating the computational resources desired by the client when executing a particular application of the client. Oftentimes, the client or the application itself will request “X” amount of processing resources (e.g., a certain number of microprocessor cores or a particular amount of processing capability) and “Y” amount of persistent storage.

To service such requests from multiple clients, cloud operators use data centers, which conventionally comprise several racks of server devices that are communicatively coupled over a local area network (LAN). Each server device comprises a respective central processing unit (CPU), and each CPU has at least one microprocessor core. Each server device additionally includes a respective persistent storage unit, such as hard disk drive (HDD) or solid state drive (SSD). A CPU of a server device resides on a motherboard, and a storage unit of the server device is coupled to the motherboard by way of a bus (e.g., via the Small Computer System Interface (SCSI), Serial Attached SCSI (SAS), Serial Advanced Technology Attachment (SATA), or other suitable interface).

There are numerous deficiencies associated with conventional data centers used by cloud operators to service clients thereof. First, cloud operators have traditionally allocated computational and storage resources in units of physical server devices. A client, however, may request computational resources at a more granular level. Traditionally, the cloud operator has handled such a request by under-utilizing computing resources on server devices in the data center. For example, a client may request processing resources associated with six microprocessor cores of a CPU in a server device of the data center, where the CPU comprises eight cores. Traditionally, the cloud operator allocates the entirety of the server device to the client, which may cause two of the eight microprocessor cores to be fallow.

Second, conventional server devices utilized in data centers include CPUs that consume relatively large amounts of power (about 1000 Watts of thermal dissipation per CPU). This further causes the data center to have cooling costs to maintain an appropriate temperature. Third, componentry of a conventional server device used in a data center is relatively expensive and complex. For example, the server device includes a motherboard, where the motherboard has a CPU thereon that must be connected to additional hardware componentry (e.g., a graphics processing unit (GPU), memory, . . . ). Due to the relatively high cost of the motherboard and componentry thereon, if an individual component of the motherboard (such as the graphics processing unit (GPU)) malfunctions, maintenance costs are incurred by removing the server from the rack, removing the motherboard from the server, removing the faulty GPU from the motherboard, placing a new GPU on the motherboard, testing the motherboard, inserting the motherboard back into the server device, repositioning the server device in the rack, and reconnecting the server device to a local area network (LAN).

SUMMARY

The following is a brief summary of subject matter that is described in greater detail herein. This summary is not intended to be limiting as to the scope of the claims.

Described herein are various technologies pertaining to an exemplary computing system architecture, where a computing system can be a data center, an enterprise server system, etc. An exemplary computing system includes a plurality of computing nodes and a plurality of data storage nodes that are disaggregated—e.g., the computing nodes can be remotely situated from the storage nodes. In such context, the term “remotely situated” is intended to indicate that the computing nodes can write data to and receive data from the storage nodes over network connections, rather than bus connections.

The computing nodes, in an exemplary embodiment, can comprise respective system on chip (SoC) modules, wherein the SoC modules can be homogeneous in nature. Each SoC module comprises at least one respective microprocessor core, a memory (e.g., random access memory (RAM) and/or read only memory (ROM)), and a network interface (e.g., a network interface controller (NIC)). Each SoC module can also optionally comprise a respective graphics processing unit (GPU) and/or other suitable modules. As the term “system on chip” implies, at least one microprocessor core, the local memory, the network interface, and (optionally) the GPU are formed on a single (common) substrate, and therefore reside on a single chip. Additionally, each computing node can additionally comprise a respective local storage module (e.g., a flash memory module) that is operably coupled to at least one microprocessor core of a respective SoC module. For example, the microprocessor core of the SoC module can be operably coupled to the local storage module by way of a bus and associated bus interface.

The above-mentioned data storage nodes can include a hard disk drive (HDD), a solid state drive (SSD), a tape drive, or some suitable combination thereof. Each storage node has a respective input/output (I/O) speed associated therewith. That is, data can be written to and read from a storage node at a particular speed. Generally, HDDs have a lower I/O speed compared to SSDs.

As noted above, the plurality of storage nodes can be operably coupled to the plurality of computing nodes by way of a suitable network connection. Each storage node is allocated bandwidth that at least matches the I/O speed of a respective storage node. Therefore, in an example, if a storage node has an I/O speed of 1 Gb/second, then such storage node is allocated bandwidth of at least 1 Gb/second. Allocation of network bandwidth in this manner ensures that a network connection between a computing node and a storage node does not act as a bottleneck for an application executing on the computing node. In an exemplary embodiment, a network that is used to operably couple the computing nodes and the storage nodes can be a full bisection network; e.g., a network in which any two arbitrary nodes can communicate at the full speeds of their network connections.

Given the above described computing system architecture, virtual motherboards can be constructed at run-time of applications. For example, an application of a client of the cloud operator can specify a certain amount of processing resources and storage resources (the amounts can be arbitrary). The cloud operator can form a virtual motherboard and a virtual storage device responsive to receipt of the specification, wherein the virtual motherboard can be backed by arbitrary, previously unallocated computing nodes (which can be an odd number of computing nodes, and the computing nodes can be positioned on different racks in the computing system), and the virtual storage device can be backed by arbitrary, previously unallocated storage nodes that are disaggregated from the computing nodes. For example, storage nodes can be positioned in different storage racks of the computing system. Since the storage nodes allocated to the application have network bandwidth allocated thereto that is at least as high as the respective I/O speeds of such storage nodes, the virtual motherboard can read data from and write data to the virtual storage device as if the computing nodes were co-located with the storage nodes.

The above summary presents a simplified summary in order to provide a basic understanding of some aspects of the systems and/or methods discussed herein. This summary is not an extensive overview of the systems and/or methods discussed herein. It is not intended to identify key/critical elements or to delineate the scope of such systems and/or methods. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

With reference now to FIG. 1, an exemplary computing system 100 that can be used by a cloud operator to provide computing and storage resources to a plurality of clients 102-104 is illustrated. The computing system 100, in an exemplary embodiment, can be a data center, in which case the clients 102-104 may be different respective companies. In another exemplary embodiment, the computing system 100 can be an enterprise server system, in which case the clients 102-104 may be divisions in an enterprise. In yet another exemplary embodiment, the computing system 100 can be a hybrid of a data center and an enterprise server system, where some computing resources are used by the cloud operator to execute enterprise applications (e.g., for internal clients), while other computing resources are used to execute applications of external clients. It is to be understood that the computing system 100 can be any suitable computing system that has the architecture described below.

The computing system 100 includes a plurality of data processing and storage resources, which will be described in greater detail below. The data processing and storage resources are allocated amongst the clients 102-104 based upon requests for such resources from the clients 102-104. Accordingly, in an example, a client may request that an application be executed in the computing system 100 that is configured to execute queries over a database maintained in the computing system 100. To that end, the client or the application can request or specify a particular amount of processing resources in connection with executing queries over the database, and can further request or specify a particular amount of storage to retain the database. As will be described in greater detail below, the computing system 100 has an architecture that facilitates servicing relatively granular requests from clients and applications, and further facilitates increased utilization of hardware when compared to conventional data center architectures.

The computing system 100 comprises a plurality of computing nodes 106-108. The plurality of computing nodes 106-108 comprise a respective plurality of system on chip (SoC) modules 110-112. Each SoC module in the plurality of SoC modules 110-112 comprises at least one respective microprocessor core, a respective memory module that is accessed by the respective microprocessor core, and a respective network interface that acts to interface a computing node with other modules of the computing system 100. Additionally, optionally, each SoC module in the plurality of SoC modules 110-112 can comprise a respective graphics processing unit (GPU) that can access the respective local memory module on the respective SoC module. The at least one microprocessor core, the local memory, the network interface, and (optionally) the GPU are formed on a single (common) semiconductor substrate—that is, the at least one microprocessor core, the local memory, the network interface, and (optionally) the GPU reside on a single chip.

The plurality of computing nodes 106-108 also optionally comprises a respective plurality of local storage modules 114-116. The local storage modules can be operably coupled to the SoC modules 110-112 by way of respective bus connections (e.g., via SCSI, SAS, SATA, . . . ). In an exemplary embodiment, the local storage modules 114-116 can be a suitable form of computer-readable data storage, such as RAM, ROM, DRAM, SRAM, PROM, EPROM, EEPROM, etc. In another example, the local storage modules 114-116 can be flash storage modules.

In an exemplary embodiment, the computing nodes 106-108 may be homogeneous in nature. In another example, the plurality of computing nodes 106-108 may comprise heterogeneous computing nodes. The computing nodes 106-108 can be placed in racks in the computing system 100 at selective positions to facilitate ambient cooling of the computing nodes 106-108. For example, the plurality of computing nodes 106-108 can be vertically stacked with space between adjacent computing nodes being between 1 inch and 3 inches, thereby facilitating airflow between computing nodes. This arrangement can enable deployment across a variety of computing system types, including air cooling and water-side cooling. In each of these arrangements the transfer of heat between nodes will occur within the space between such nodes.

The computing system 100 further comprises a plurality of storage nodes 118-120. The storage nodes 118-120 can be or include hard disk drives (HDDs), solid state drives (SSDs), tape drives, or other suitable storage devices.

The computing system 100 further includes a computing system network 122, over which the computing nodes 106-108 can transmit data to and retrieve data from the storage nodes 118-120. In an exemplary embodiment, the network 122 can be a full bisection bandwidth network. A fill bisection bandwidth network is a network that, regardless of where the network 122 is dissected, nodes on one side can send data at full bandwidth to nodes on the other side, and vice versa. This property allows for an arbitrary computing node or subset of arbitrary computing nodes from the plurality of computing nodes 106-108 to transmit and receive data at full bandwidth to and from an arbitrary storage node or subset of arbitrary storage nodes from the plurality of storage nodes 118-120.

In an exemplary embodiment, each storage node in the plurality of storage nodes 118-120 can have a respective network bandwidth allocated thereto that is equal to or greater than the I/O speed of a respective storage node. For example, if the first storage node 118 is a HDD with an I/O speed of 1 Gb/second, network bandwidth allocated to the first storage node 118 is at least 1 Gb/second. In another example, if the nth storage node 120 is a SSD, and has an I/O speed of 3 Gb/second, network bandwidth allocated to the nth storage node 120 is at least 3 Gb/second. The network 122 comprises suitable network equipment and has a topology that allows for such network 122 to be a full bisection bandwidth network. Thus, the network 122 can include routers, switches, cabling, devices that facilitate optical communication, etc.

The computing system 100 can further include a stager computing device 124 that is configured to allocate computing nodes and/or storage nodes to the clients 102-104 (e.g., applications to be executed for the clients 102-104) responsive to receipt of requests for processing resources and/or storage resources from at least one of the clients 102-104 or the applications. In an exemplary embodiment, the first client 102 can transmit a request to the computing system 100 by way of a network 126 (e.g. the Internet), wherein the request is for processing resources corresponding to two computing nodes and storage resources corresponding to three storage nodes. The stager computing device 124 can receive the request and access a database maintained at the computing system 100 that identifies which of the computing nodes 110-112 have not been allocated and which of the storage nodes 118-120 have not been allocated. When there are a sufficient number of unallocated computing nodes and storage nodes to service the request from the first client 102, the stager computing device 124 can allocate the requisite number of computing nodes (from amongst the unallocated computing nodes) and the requisite number of storage nodes (from amongst the unallocated storage nodes) to the first client 102.

Thus, continuing with this example, the stager computing device 124 can aggregate two (arbitrary) computing nodes in the plurality of computing nodes 106-108 responsive to receipt of the request from the first client 102, thereby generating a virtual motherboard. Such virtual motherboard presents a single virtual execution platform to an application of the first client 102. Likewise, the stager computing device 124 can create a virtual storage device by aggregating three previously unallocated (arbitrary) storage nodes for the first client 102. The stager computing device 124 can dynamically bundle the storage nodes for the application of the first client 102 at runtime.

It is again to be noted that the computing nodes 110-112 and the storage nodes 118-120 are disaggregated in the computing system 100. That is, the computing nodes 110-112 can be positioned in a first set of racks, and the storage nodes 118-120 can be positioned in a second set of racks that is non-identical to the first set of racks. The computing nodes allocated to the first client 102 can be positioned on different racks, and the storage nodes allocated to the first client 102 can be positioned on different racks. The high-bandwidth of the network 122 allows for the computing nodes allocated to the first client 102 to be, in a sense, arbitrary, as the computing nodes need not be co-located on a same rack. The same holds true for the storage nodes. A similar process can be undertaken with respect to the pth client 104. In other words, the pth client 104 can submit a request to the computing system 100, wherein the request indicates a desired amount of processing resources and a desired amount of storage resources. The stager computing device 124 can select unallocated computing nodes and unallocated storage nodes to service the request, creating for the pth client 104 a virtual motherboard backed by the computing nodes and a virtual storage device backed by the storage nodes.

The exemplary computing system 100 exhibits numerous advantages over conventional data centers and enterprise server systems. For example, the computing system 100 may be associated with more efficient resource utilization compared to conventional data centers and enterprise server systems, as processing resources and storage resources can be allocated to client at a relatively granular level. For instance, conventionally, a data center is unable to adequately service a request from a client for an odd number of microprocessor cores. In an example, in a conventional data center, if an application of a client that is to be executed at the data center sets forth a request for processing resources corresponding to three microprocessor cores, the data center may deny the request or allocate four microprocessor cores to the client, thereby causing one of the processor cores to be fallow while still consuming power. In contrast, the computing system 100 facilitates creation of virtual motherboards that can be backed by an arbitrary number computing nodes from amongst the plurality of computing nodes 106-108, selected from arbitrary locations in the computing system 100.

Therefore, if the application of the client requests processing resources corresponding to an odd number of microprocessor cores, the stager computing device 124 can create a virtual motherboard for the application that is backed by the odd number of computing nodes. Similarly, if the application of the client requests processing resources corresponding to an even number of processor cores, the stager computing device 124 can create a virtual motherboard for the application that is backed by the even number of computing nodes. Likewise, the architecture of the computing system 100 facilitates creation of virtual storage devices that can be backed by an arbitrary number of storage nodes from amongst the plurality of storage nodes 118-120, selected from arbitrary locations in the computing system 100.

In addition, the computing system 100 can be associated with simplified administration. Specifically, since the computing nodes are disaggregated from the storage nodes, entire racks or containers of homogeneous computing nodes and/or storage nodes can be placed in the computing system 100 or removed from the computing system 100 at once. In contrast, updating computing or storage resources of traditional aggregated servers requires specialized maintenance (e.g., for each server).

Still further, the computing system 100 can be associated with a reduction in power consumption compared to conventional data centers or enterprise server systems. For instance, the computing nodes 106-108 may have similar power needs, as the computing nodes 106-108 may be homogeneous. Furthermore, as noted above, the computing nodes 106-108 can be laid out to maximize ambient cooling.

With reference now to FIG. 2, an exemplary computing node 200 in the plurality of computing nodes 106-108 is illustrated. The computing node 200 includes a SoC module 202 and associated local storage 204. The SoC module 202 includes a microprocessor core 206, a memory 208, a network interface 210, and (optionally) a GPU 212. The microprocessor core 206 and/or the GPU 212 can be operably coupled to the local storage 204 by way of a bus. It can be ascertained that the microprocessor core 206, the memory 208, the network interface 210, and the GPU 212 are formed on a single common semiconductor substrate. In an exemplary embodiment, the computing node 200 can be placed in a container or rack with a plurality of other homogeneous computing nodes. For example, the rack may include 10 computing nodes (which are homogeneous with the computing node 200), wherein each computing node is provided with a network connection having a particular amount of bandwidth. For instance, each computing node may have at least a 1 Gb/second Ethernet connection.

With reference to FIG. 3, an exemplary storage server 300 is illustrated. The storage server 300 may comprise a plurality of storage nodes 302-304, wherein the storage nodes 302-304 may be homogeneous storage nodes. For example, the storage nodes 302-304 may be a plurality of SSDs. Furthermore, in an example, the computing system 100 may include two or more different types of storage servers: a first storage server that includes SSD storage nodes, and a second storage server that includes HDD storage nodes. The storage server 300 can include a motherboard 306, wherein the motherboard 306 can include a native CPU chipset that provides SATA ports for the storage nodes 302-304. As noted above, the storage nodes 302-304 can be connected to the computing nodes 106-108 over the computing system network 122 (e.g., a full bisection bandwidth network). The storage server 300 is provided with a sufficient amount of network bandwidth, such that each storage node therein can be read from and written to at full speed over the network 122. The full bisection bandwidth network that can match storage speeds with network speeds creates a locality oblivious storage substrate. That is, any computing node can access any storage device at full speed, regardless of their respective locations in the computing system 100.

Now referring to FIG. 4, a functional block diagram of the stager computing device 124 is illustrated. The stager computing device 124 includes a request receiver component 402 that receives a request from at least one of the clients 102-104. As noted above, the request can indicate an amount of processing resources and/or storage resources desired by the client for executing an application on computing nodes and storing data on storage nodes of the computing system 100. The stager computing device 124 further comprises an allocator component 404 that can allocate computing nodes and/or storage nodes from the computing nodes 106-108 and the storage nodes 118-120 to service the request from the client.

To that end, the stager computing device 124 can include a data store 406 that comprises allocation data 408. The allocation data 408 can indicate which of the computing nodes 106-108 and which of the storage nodes 118-120 are not already allocated to clients of the cloud operator. The allocator component 404 can select a subset of the computing nodes 106-108 for allocation to the client that can service the request, wherein computing nodes in such subset are not allocated to other clients of the cloud operator. Likewise, the allocator component 404, through analysis of the allocation data 408, can identify a subset of storage nodes from the storage node 118-120 that are not allocated to other clients of the cloud operator and that can service the request from the client. The allocator component 404 can then allocate the subset of storage nodes to the client.

Accordingly, when an application is to be executed on behalf of the client, the stager computing device 124 can create a virtual motherboard and a virtual storage device for the application to use. The allocator component 404 provides the application with enough computing nodes and storage nodes to meet its computational and storage needs. The allocator component 404 can expose the virtual motherboard and the virtual storage system in a variety of manners. For example, the computing nodes can be exposed as a virtual non-uniform memory access (NUMA) motherboard, in which microprocessor cores communicate using a virtual bus layered atop their respective network connections (e.g., 1 Gb/second Ethernet connections). The physical disks can be exposed to an application using one or more virtual disks, such that each virtual disk is backed by one or more physical storage nodes.

Now referring to FIG. 5, exemplary creation of a virtual motherboard and a virtual storage device is illustrated. A computing system 500 includes four computing nodes 502-508 and six storage nodes 510-520. The stager computing device 124 receives a request from a client 522, wherein the request pertains to an application being executed using the resources of the computing system 500. For example, the request can indicate that the application needs processing resources of two computing nodes, and the request can further indicate that the application needs storage resources corresponding to two storage nodes. The stager computing device 124 can ascertain that the first computing node 502 and the fourth computing node 508 are unallocated, while the computing nodes 504 and 506 have been allocated to another client (e.g., another application is utilizing the computing nodes 504 and 506). The stager computing device 124 can cause a virtual motherboard to be constructed that is backed by the first computing node 502 and the fourth computing node 508, which were previously unallocated. It can be ascertained that the first computing node 502 and the fourth computing node 508 are not shown as being adjacent to one another in the computing system 500. Such computing nodes 502 and 508 can be arbitrarily located in the computing system 500.

The stager computing device 124 can further ascertain that the first storage node 510, the third storage node 514, the fourth storage node 516, and the six storage node 520 have been allocated to at least one other client of the cloud operator, while the second storage node 512 and the fifth storage node 518 are unallocated. The stager computing device 124 can then construct a virtual storage device that is backed by the previously unallocated storage devices 512 and 518. Again, it is noted that the storage nodes 512 and 518 need not be co-located in the computing system 500. For instance, the storage nodes 512 and 518 may be located in separate storage servers. The application may then be executed using the computing nodes 502 and 508, wherein the application is provided with an address or addresses corresponding to the storage nodes 512 and 518.

FIGS. 6-7 illustrate exemplary methodologies relating to computing systems and constructing virtual motherboards and virtual storage devices. While the methodologies are shown and described as being a series of acts that are performed in a sequence, it is to be understood and appreciated that the methodologies are not limited by the order of the sequence. For example, some acts can occur in a different order than what is described herein. In addition, an act can occur concurrently with another act. Further, in some instances, not all acts may be required to implement a methodology described herein.

Moreover, the acts described herein may be computer-executable instructions that can be implemented by one or more processors and/or stored on a computer-readable medium or media. The computer-executable instructions can include a routine, a sub-routine, programs, a thread of execution, and/or the like. Still further, results of acts of the methodologies can be stored in a computer-readable medium, displayed on a display device, and/or the like.

Now referring to FIG. 6, an exemplary methodology 600 for designing a computing system is illustrated. The methodology 600 starts at 602, and at 604 a plurality of SoC modules are provided. As noted above, a SoC module includes a microprocessor core, a memory, and a network interface. At 606, a plurality of data storage nodes are provided. With more specificity, a plurality of storage server devices can be provided, wherein each storage server device includes a respective plurality of data storage nodes. At 608, the SoC modules and the data storage nodes are communicatively coupled using a full bisection bandwidth network. As noted above, each storage node can be allocated bandwidth that corresponds to its maximum I/O speed. The methodology 600 completes at 610.

Now referring to FIG. 7, an exemplary methodology 700 for constructing a virtual motherboard and a virtual storage device is illustrated. The methodology 700 starts at 702, and at 704 a request for processing and storage resources is received at a computing system from a client of an operator of the computing system. The request includes data that indicates processing resources and/or storage resources for executing an application for the client at the computing system. At 706, a plurality of unallocated computing nodes are identified responsive to receiving the request at 704. As noted above, each computing node comprises a SoC module. Additionally, a plurality of unallocated storage nodes are identified responsive to receiving the request. At 708, the plurality of computing nodes and the plurality of storage nodes are allocated to the client. With more specificity, the plurality of computing nodes are stitched together to form a virtual motherboard, and the plurality of storage nodes are stitched together to form a virtual storage device. The virtual motherboard executes the application, transmitting data to and retrieving data from the virtual storage device. Accordingly, the plurality of computing nodes can be exposed to the client as a virtual NUMA motherboard. Data that identifies the storage nodes can be provided to the plurality of computing nodes, thereby allowing the computing nodes to transmit data to and retrieve data from the storage nodes when executing the application for the client. Alternatively, another layer of abstraction can be provided, where the computing nodes are provided with contiguous address space that is then mapped to the storage nodes. Furthermore, as indicated above, each storage node is allocated network bandwidth corresponding to its maximum I/O speed. Therefore, the plurality of storage nodes are allocated bandwidth corresponding to the aggregate of the maximum I/O speeds of such storage nodes. The methodology 700 completes at 710.

Referring now to FIG. 8, a high-level illustration of an exemplary computing device 800 that can be used in accordance with the systems and methodologies disclosed herein is illustrated. For instance, the computing device 800 may be used in a system that supports allocating computing nodes and storage nodes to a client of a cloud operator.
